I recently acquired an HBR-13C in stunning condition. The HBR-13C was described in QST magazine 1965, a 13 tube superhetrodyne receiver, that anyone with (and these are my words) 'above average skills' can build :) Its designer, Ted Crosby, achieved near cult status as a result of his HBR designs from the late 50's to mid 60's.
My 13C came with one set of coils, 15 meters, but none for my favorite bands. The coil forms used in the HBR series was the clear Amphenol 1 1/4" diameter five pin form. There is a 'band' around the top of the coil form that is slightly wider than the windings part of the form. This wider band allows an air variable capacitor to sit down into it. The builder of my 13C used what appears to be RTV to hold the cap ends securely in place. The HBR uses three coils per band, and I want to wind 80, 40, 20 meters. Does anyone on here have any of these clear Amphenol coil forms for sale? I'm going to initially try and find the clear forms to keep up with the spirit of the HBR. Oddly, the clear coils look cool as well. I can easily imagine my coils plugged into a nice oak base while other bands are in use. Gads I think I need BA intervention :))))) Are these coil forms unobtainium? 73, Scott WA9WFA
